DRILL-CUP.

Specification of Letters Patent.

Patented March 6, 1906 Application filed April 11, 1905. Serial No. 255,038.

To all whom it may concern:

Be it known that I, ALBERT W. PERRY, of Northville, Spink county, South Dakota, have invented certain new and useful Improvements in Drill-Cups, of which the following is a specification.

My invention relates to improvements in grain-drills, and particularly in the wheels or feeding the grain from the feed-cups as the machine moves over the field.

The object of the invention is to provide a wheel that will not clog and stop the feed should a nail, pebble, or other foreign material pass down into the cup with the grain.

A further object is to provide a wheel that is easily accessible for the purpose of examination or to remove any foreign material that may have lodged in the cup surrounding the same.

A further object is to provide a wheel that will have a positive and uniform feed and one that will operate effectively under all conditions and will feed any kind of grain.

The invention consists generally in a feedcup and a feed-wheel operating therein and dished or hollowed out on one side and provided with a series of shallow grooves that extend tangentially with respect to the axis of the wheel toward the periphery thereof.

Further, the invention consists in a removable feed-cup inclosing the wheel and from which the grain is lifted by the revolution of the wheel.

Further, the invention consists in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a transverse sectional view through a drill-hopper, showing the position of the feed-cup and its wheel beneath. Fig. 2 is a sectional view on the line y 'y of Fig. 1. Fig. 3 is a detail view looking at one of the wheels and its cup and illustrating the manner of securing the cup to the bottom of the drill-hopper. Fig. 4 is a transverse sectional view through the drillhopper and the feed-cup beneath, and Fig. 5 is a sectional view on the line :10 as of Fig. 1.

In the drawings, 2 represents a drill-hopper of the ordinary style mounted, as usual, upon a wheeled axle and wherein the grainto be sown is placed. The supports for the drill-hopper being of common construction are all omitted in the drawings, as they form no part of my present invention.

3 is a shaft extending across the machine beneath the drill-hopper and geared to the machine axle or wheels in any suitable manner, and upon this shaft I provide a series of feed-wheels 4, secured in any suitable way and in the form of dish-shaped disks arranged to revolve with said shaft in a vertical plane and each provided on its concave surface with a series of shallow grooves 5, that are tangentially arranged with respect to the axis of the disk and extend to the periphery thereof. I have only shown two of these disks on the shaft 3 but it will be understood that there are a series of them secured on said shaft at intervals, the number depending upon the width of the machine. A feed-cup 6 is provided having a spout 7, whose open end is adapted to fit snugly against the bottom of the hopper 2 around a discharge-opening 8 therein, the bottom of said drill-hopper being inclined toward said opening to facilitate the discharge or flow of the grain therein, as usual in machines of this kind. A flange 9 preferably surrounds the upper end of the spout 7 and is provided on one side With a lug 10, fitting into a socket 11, secured on the bottom 2. A button 12, mounted on the bottom of the drill-hopper, is arranged to swing around under the fia'nge 9 on the side of the feed-cup opposite from the lug 10 and aid in holding the cup in place against the bottom of the drill-hopper, but allow its ready removal independently of all the other cups whenever desired. The operator is thus able to obtain access to each feed-wheel at any time while the machine is in use in the field without the use of special tools and without the necessity of removing or disturbing any of the other wheels or parts of the machine.

The spout 7 leads down into a pocket 13 at the lower end of the feed-cup, and within this pocket the feed-wheel 4 operates, the walls of the pocket conforming to the surface of the wheel on one side to allow space for the grain to flow into and contact with the roughened dish-shaped inner surface of the wheel. An opening is provided in the upper rear wall of the pocket 13, and a ledge 14 is provided at the edge of said opening near the roughened surface of the wheel and whereon the grain is discharged from the wheel and al lowed to drop upon the ground. The grooves in the concave face of the feed-wheel are so arranged, as indicated in Fig. 4, that they will pick up the grain in the bottom 0f machine without any danger of clogging or breaking any of the parts or interrupting the operation of the machine. Grain and seeds of all kinds may be fed by this wheel with equal facility. Its feed is positive and uniform, and there are no delicate parts that are likely to become broken or damaged, and in case of accident to a wheel its examination is permitted, and at any time a feed-cup can be removed for inspection or to substitute another. v

A tube 15 is arranged to fit around the edge of the ledge 14 and receive the grain therefrom, and the upper end of this tube extends above the ledge and acts as a wind-break to prevent the seeds from being blown away or scattered around the machine. The wheels are preferably made right and left and oppositely arranged on each side of the center, so that the driver sitting in the middle of the machine can look each way and watch the feed of the wheels and discover at once if the feed of any one of the wheels should be stopped through clogging of the grain in a feed-cup.

I claim as my invention 1. The combination, with a drill-hopper having a discharge-opening, of a feed-cup supported beneath said opening and having a pocket in its lower end, a feed-wheel operating in said pocket and having a concave face provided with a series of tangential grooves and said cup having agrain passage which allows the unobstructed descent of the grain from said hopperinto said pocket and grooves.
